  • Publication number: 20140251578
    Abstract: The adjustable heat exchanger provides precise control of oven temperature in a pyrolysis reaction. The heat exchanger includes two sets of hollow non-circular discs, the discs of a movable set being interleaved with the discs of a stationary set. A first working fluid circulates through a heat source oven and through the hollow stationary discs, and a second working fluid circulates through the hollow rotating discs and a pyrolysis oven. The two fluids do not mix with one another, but are always completely separate from one another. Heat transfer depends upon the relative surface area of the rotary discs interleaved between the stationary discs. Minimum heat transfer occurs when the rotary discs are rotated to a position clear of the stationary discs, and maximum heat transfer occurs when the rotary discs are completely interleaved with the stationary discs.

The heat exchanger comprises multiple heat exchange tubes formed of flexible material in a shape that permits them to be lengthened or shortened by simply moving the headers toward or away from each other. Preferably, the tubes are formed of a flexible, non-resilient material such as copper, and are shaped in a serpentine or helical manner. In this way, the tubes can be drawn out to elongate the heat exchanger or compressed to shorten it, depending on the dimension of the cooling coil in the air handler.

  • Patent number: 8480900
    Abstract: A buoyant water heating device that may be used in a natural setting, such as a pond or lake, or in a man-made water-containing apparatus, such as a pool or water-treatment lagoon. The device comprises a water-filled, generally cylindrical anchor member coupled to a hollow, generally annular base member, and may he used alone or in combination with multiple other devices to create a free-floating blanket on the surface of the water. The device absorbs solar energy to heat water external to the device, and also provides a layer of thermal insulation between the water and the air above the device.

  • Patent number: 8418484
    Abstract: A heat exchanger for exchanging heat between gasses such as air and a liquid or gaseous coolant has narrow spacing between exchanger surfaces for high efficiency. To avoid undue obstruction of gas flow due to ice buildup on the exchanger surfaces, the heat exchanger is equipped with sensors to monitor the gas flow and an actuator that widens the spacing between exchanger surfaces such that gas flow remains unimpeded. Embodiments provide for defrosting of the exchanger surfaces when an limit on spacing of exchanger surfaces is reached, and for relaxing the spacing to the original narrow spacing when defrosting is completed.

  • Publication number: 20130043238
    Abstract: A solids heat exchanger (10) is in the form of a shell and tube arrangement having a shell section (11) through which heated oil (12) passes and a tube section (13). A screw conveyor (14) extends along its length and has a drive motor (15). Drill cuttings or other hydrocarbon contaminated materials are fed in through an inlet (16) and then conveyed along the tube (13) where heat transfer takes place. On exiting the tube (13) oil and water vapour rises and escapes through a first outlet (17) while the now cleaned drill cuttings or other materials fall through a second outlet (18) forming a discharge zone. The apparatus aims to reduce the oil content of the solids to less than 0.5%. The solids can then simply be disposed of. The base oil can be reclaimed and reused.
